摘　　要：该文对二苄叉丙酮的制备实验进行了改进。用分子筛固载氟化钾代替氢氧化钠作催化剂,研究了醛酮物质的量之比、催化剂用量和溶剂对产率的影响,确定了最佳合成条件。The experiment for preparation of bis-Benzalacetone has been improved by using KF supported on molecular sieve to substitute for NaC1 as the catalyst. In order to determine the optimum synthesis condition, the paper studied the mol ratio of aldehyde and ketone and the affect of the amount of the catalyst and the solvent on productivity.
